LAND-MARKER.

Specification of Letters Patent.

Patented May 9, 1916.

Application led December 8, 1915. Serial No. 65,777.

To all whom t may concer/n Be it known that I, Bier-IARD V. BARRY, a citizen of the United States, residing at Ottumwa, in the county of VVapello and State of Iowa, have invented new and useful lmprovements in Land-Markers, of which the following is a specification.

My present invention pertains to land markers such as are ordinarily used on corn planters and the like; and it consists in the peculiarl and advantageous transverse bar for connection with a planter frame, in the connections of the marker arms to said bar, and inthe runners with which the arms are equipped, all as hereinafter described and definitely claimed.

In the accompanying drawings which are hereby made a part hereof: Figure 1 is a broken elevation showing the transverse bar and portions of the marker arms thereon. Fig. Qi is a transverse section of the transverse bar. Fig. 3 is an enlarged detail view, partly in elevation and partly in` section, showing one of the marking arms, its equipment and the connection of the arm to the transverse bar.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The transverse frame bar 1 of my improvement is made of metal and of angular form in cross-section, Fig. 2, with a forward rounded corner 2 which is advantageous because it precludes the possibility of knots on the wire (not shown) catching against the bar. Said bar 1 comprises a middle portion 3, Fig. 1, designed to be connected to a planter frame at the back thereof in the manner well known in the art, intermediate portions l1 extending outwardly and downwardly at oblique angles to the portion 3, and end portions 5 extending outwardly from the outer ends of the portions 4. By reason of the transverse bar being provided with the drop or downwardly-inclined portions 4, it will be observed that the inner connected ends of the marking arms 6 are disposed at a slight distance above the ground which is advantageous because of the facility with which said arms can be put into and out of operation.

At their outer ends of the portions 5 of the bars 3 are provided with reduced portions 7, of circular form in cross-section. These portions 7 extend downwardly and inwardly from the portions 5 and terminate at their lower ends in short vertically-dis posed portions S on which are mounted washers 9, supported by cotter pins 10.

The major portion of each marker arm 6 1s preferably of tubular form as indicated by 11 in Fig. 3, and at its inner end each tubular portion 11 is provided with a female member 12 complementary to the portion 7 at one end of the transverse bar 3. The said member 12 is provided with a shank 13 secured in the inner end of the tubular portion; and it is also provided with an aperture 141 receiving the portion 7, and a beveled inner end 15, all as clearly illustrated in Fig. 3. The aperture 14 is generally speaking, increased in size upwardly, and said aperture may be specifically described as having longitudinal side walls 16 which are disposed vertically, a short inner end wall 17 that describes an obtuse angle, and an outer wall 18 which is inclined upwardly and outwardly. By virtue of the said aperture 14, it will be manifest that the marker arm can be readily swung upwardly until the beveled end 15 brings up against the washer 9. It will also be manifest that because of the elongated aperture 14: having the parallel vertical walls 16 fitting snugly against the inclined portion 7 in combination with the said portion 7, inward movement of the arm 6 will be attended by the raising of the outer end thereof, while outward movement of the arm 6 will be accompanied by downward movement of the outer end thereof. When in working position, the marker arm can rest on the washer 9 as illustrated in Fig. 3, it not being necessary for the weight of the arm 6 to be imposed on the runner 19 with which each marker arm is equipped, for reasons which will hereinafter be set forth.

As shown at the right of Fig. 3, each runner 19 is curved in the direction of its width in order to cause the runner to draw and ho-ld itself in the ground. rlhe runner 19 is suitably-clamped at 20 on its complementary marker arm, and consequently the run ner can be set to any degree of pitch, according to the condition of the ground to be marked.

The general operation of the marking arms, which are designed to be connected together through the medium of a cable 21, is similar tothe marking arms common in the art; and it is therefore unnecessary to reiterate such operation herein.

Having described my invention, what I claim and desire to secure by Letters-Patent is:

l. In means for the purpose described, the combination of a metallic frame bar, of right-angle in cross-section and rounded at its forward corner; said bar being adapted to be arranged transversely on and connect ed with the frame of a planter and having a middle portion and dropped end portions and terminating in downwardly and inwardly inclined and reduced portions, of circular form in cross-section, washers supported on said reduced portions near the lower' ends thereof, and marker arms having elongated apertures receiving said reduced portions; said apertures having side walls that bear snugly against said reduced portions, and the arms being beveled at the undersides of their inner ends.

2. In means for the purposes described, the combination of a transverse bar having a downwardly and inwardly inclined and reduced portion, of circular form in crosssection, and also having a short vertically-l disposed portion at the lower end of said inclined portion, a washer supported on the lower vertical portion adjacent to the upper end thereof, and a marker arm receiving the inclined portion and supported on the washer and having an inner end beveled at its under side and also having its receiving aperture gradually increased upwardly, substantially as and for the purpose set forth.

3. In means for the purpose described, the combination of a transverse bar having a downwardly and inwardly inclined and reduced portion, of circular form in cross-V section, a washer supported on the lower end of said portion, and a. marker arm having an elongated aperture receiving said portion; said aperture having side walls that bear snugly against said portion, and the arm being beveled at the underside of its inner end. v

4l. In a planter' attachment, a frame bar comprising a middle horizontal portion constructed and arranged to be disposed transversely on and connected with the frame of a planter, and dropped end por-Y tions iixedwith respect to and arranged 1n.
